ADDRESSABLE 28-LINE DECODER/DRIVER

Intended for use in ink-jet printer applications, the A6817SEP addressable 28-line decoder/driver combines low-power CMOS inputs and logic with 28 high-current, high-voltage bipolar outputs. A 4-to-14 line decoder determines the selected output driver (n) in each 14-driver bank. Two independent output-enable inputs (active low) then provide the final decoding to activate 1- or 2-of-28 outputs (OUTAn and/or OUTBn). Special internal circuitry is programmed at the time of manufacture to adjust the output pulse timing and thereby the energy the device delivers to the ink-jet print head. The DABiC-IV A6817SEP directly replaces the original BiMOS-II A5817SEP in most applications.
